[PATCH v4 0/3] gnss: ubx: support the reset pin of the Neo-M8 variant

[PATCH v4 0/3] gnss: ubx: support the reset pin of the Neo-M8 variant

[Wolfram Sang]

The Renesas KingFisher board includes a U-Blox Neo-M8 chip with its
reset pin wired to a GPIO. To support that, we need "reset-gpio" support
(patches 2+3). But first, simplify regulator handling with a new helper
(patch 1).

Changes since v3:
* rebased to 6.6
* improved commit messages for patches 2+3


Wolfram Sang (3):
  gnss: ubx: use new helper to remove open coded regulator handling
  dt-bindings: gnss: u-blox: add "reset-gpios" binding
  gnss: ubx: add support for the reset gpio

[PATCH v4 2/3] dt-bindings: gnss: u-blox: add "reset-gpios" binding

[Wolfram Sang]

The Renesas KingFisher board includes a U-Blox Neo-M8 chip. This chip
has a reset pin which is also wired on the board. Introduce a binding to
support this reset pin.
